STEAM-SELPARATOR.

SPECIFICATION forming part of Letters Patent No. 619,308, dated February 14, 1899. Application filed June 27,1898. Serial No. 684,543. (No model.)

To all whom 15 may concern.-

Be it known that I, RICHARD I-IUTCHISON, a resident of Boston, in the county of Suifolk and State of Massachusetts, have invented certain new and useful Improvements in Steam- Separators, of which the following is a speciiication.

Myinvention has relation to what is known as a steam-separator, and is adapted for usein connection with feed-Water heaters and purifiers and the like Where oil and water are separated and also in connection with boilers and the like where water is separated from the steam in order to insure perfectly dry steam.

The object of my invention is to provide a separator to subserve the above purposes, which separator shall be simple in its construction and eflicient and reliable in its operation.

In the drawings, Figure l is a sectional plan view on line 1 of Fig. 2; Fig. 2, an elevation of my device, and Fig. 3 a sectional elevation on line 3 of Fig. 1.

My separator is preferably formed from two castings 1 and 2, forming a separating-chamber 3 and a receiving-chamber 4 with a communicating passage 5. These chambers may be of any suitable shape and dimensions as may be found necessary or desirable. The separating-chamber is provided with an inlet 6 for live or exhaust steam, as the case may be, depending upon whether the separator is used in connection with a boiler or with a feed-Water heater and purifier, and such chamber is also provided with an outlet 7.

Within the separating-chamber is arranged a diaphragm or partition substantially in the form of a double spiral, which is preferably,

though not necessarily, corrugated. The ob-` ject of this arrangement is to provide a passage of such a nature as to eifectually separate oil or Water, or both, from the steam Without materially affecting or impeding its iiow.

The first partition S starts from the Wall of the separating-chamber, preferably at a point opposite the inlet and adjacent to the outlet, as shown at 9 in Fig. l, and extends in a spiral path substantially to the center of the separating-chamber. The second partition or diaphragm 10 is made the reverse of the first spiral and starts from substantially the center of the separating-chamber near the inner end of the rst partition, but separated therefrom to form a passage for the flow of the steam, and runs spirally to a point substantially opposite the outlet and adjacent to the inlet of the separating-chamber. The preferably corru gated material of the spirals may be located upon the side Walls of the separating-chamber, as at 12 and 13, and in such case these side pieces may be extensions of the spirals themselves. In order to retain these partitions in place, the top and bottom of the separating-chamber are provided With suitable spiral grooves let to receive the partitions, asl

clearly illustrated in Fig. 3. When the steam enters the separating-chamber, it is caused to traverse a spiral path in one direction and then by a quick turn at or near the center of the separating-chamber to traverse a spiral path in a reverse direction. During the entire travel of the steam in the separating-tank it is also subjected to the action of centrifugal force, so that such force, in addition to the sharp reversal in the direction of fiow of the steam, causes all the oil and Water to be separated from the steam and permitted to flow through the passage 5 into the receivingchamber 4.

While the corrugations in the partitions are not essential, yet they may aid somewhat in the separating operation and may be found desirable in many, it' not all, instances. By means of these spiral. partitions the steam is also caused to travel a distance which is considerable in proportion to the size and diameter of the separating-chamber, and during this extended travel the separating operation is continuous, whereby the oil and water are thoroughly separated from the steam.

Although I have described more or less precise forms and details of construction, I do IOC cally in such chamber and connected With the top and bottom thereof.

2. Asteam-separatorcomprisingachamber having an inlet and an outlet, a double and reverse spiral partition arranged vertically in such chamber and connected with the top and bottom thereof, and a drain or outlet at substantially the central part of the bottom of such chamber and at the pointof reversal of the spiral partitions. A

3. A steam-separator comprisinga chamber with an inlet and outlet, a spiral partition therein extending substantially to the center of the chamber, a second partition extending in a reverse spiral from substantially the center toward the outlet, a receiving-chamber, and an opening communicating between the chambers and located substantially at the center of the bottom of the separating-chamber where the inner ends of the spirals approach.

4. A steam-separator comprising a chamber with an inlet and outlet, a substantially vertical diaphragm or partition starting from the inner Wall of the chamber opposite the inlet and adjacent to the side of the outlet and extending spirally toward the center of such chamber, a second diaphragm or partition starting near the inner end of the irst partition but separated therefrom to form a passage and extending spirally to a point substantially opposite the outlet and adjacent to the inlet, both of said partitions extending from top to bottom of said chamber.

5.y A steam-separator comprising a separating-chamber with an inlet and outlet, a double spiral diaphragm or partition in the chamber extending from topto bottom thereof, one coil or spiral extending substantially to the center and the other coil extending from substantially the center and adjacent to the inner end of the rst coil but leaving a passage thereat, a receiving-chamber located substantially below the separating-chamber, suchlatter chamber having an outlet'arranged substantially at the cen ter of the bottom and communicating with the receiving-chamber.

6. A steam-separator comprising a separating-chamber having an inlet and outlet and two spiral partitions arranged therein the reverse of each other and each extending from the side Wall ofy the chamber to a point near the center, the top and bottom of the interior. of the chamber having channels or grooves to receive the partitions.

7. A steam-separator comprising a separating-chamber having an inlet and outlet, a

'corrugated spiral partition therein extending substantially to the center of the chamber, a second corrugated spiral partition therein forming a continuation of the path of the steam but in a reverse spiral, corrugated material located upon the side walls of the separating-chamber'and a receiver for collecting the oil and water separated such recess having a passage connecting with the separatingchamber substantially at its center at the point of reversal of the spiral travel of the steam through the chamber.

8. A steam-separator comprising a casing 1 having a separating-chamber 3 with an inlet 6 and outlet 7, a diaphragm or partition 8 running from top to bottom of said chamber and extending spirally toward the center of thel separating-chamber, a second diaphragm or partition l0 therein in reverse spiral and running from top to bottom of said chamber, a casing 2 having a receiving chamber 4 and an outlet 5 in the separating-chamber communicatin g with the receiving-chamber.

9. Av steam-separator comprising a casing l having a separating-chamber 3 with an inlet 6 and outlet 7, a diaphragm or partition S running from top to bottom of said chamber and beginning in the chamber at 9 and extending spirally toward the center of the chamber, a second diaphragm or partition l0 running from top to bottom of said chamber and extending from substantially the center of the chamber to a point ll therein, an outlet 5 substantially at the center of the chamber, a receiver 2 having a chamber 4 into which the.

outlet 5 enters.

l0. A steam-separator comprising a casing l having a separating-chamber 3 with an inlet 6 and outlet 7, a diaphragm or partition S running from top to bottom ot' said chamber and extending spil-ally toward the center of the chamber, a diaphragm or partition 10 running from top to bottom of said chamber and extending in a reverse spiral from a point adjacent the center of the chamber, the ends 12 and 13 of the partitions respectively extending along opposite side Walls of the chamber, and a receiver 2 having a chamber 4 and a passage rcommunicating with the separatingchamber, such latter chamber having grooves to receive the spiral diaphragms or partitions.
